riscv: canaan: remove useless select of non-existing config SYSCON

The config SYSCON never existed in the kernel repository; so, the select of
that config in ./drivers/soc/canaan/Kconfig has no effect.

Presumably, this was just some mistake, assuming some symmetry in handling
and naming of configs that simply does not exist.

Remove this useless select of a non-existing config.

drivers: bus: Delete CONFIG_SIMPLE_PM_BUS

The simple-pm-bus driver is mandatory for CONFIG_OF based platforms to work
with fw_devlink. So, always compile it in for CONFIG_OF and delete the
config since it's no longer necessary.

clk: Add RISC-V Canaan Kendryte K210 clock driver

Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC.
This new driver with the compatible string "canaan,k210-clk" implements
support for the full clock structure of the K210 SoC. Since it is
required for the correct operation of the SoC, this driver is
selected by default for compilation when the SOC_CANAAN option is
selected.

With this change, the k210-sysctl driver is turned into a simple
platform driver which enables its power bus clock and triggers
populating its child nodes. The sysctl driver retains the SOC early
initialization code, but the implementation now relies on the new
function k210_clk_early_init() provided by the new clk-k210 driver.

The clock structure implemented and many of the coding ideas for the
driver come from the work by Sean Anderson on the K210 support for the
U-Boot project.
